June, 1913] Banks: Notes on African Myrmeleonid^. 155 



Gandulus leptogaster Navas. 



This is Ncurolcon filiformis Gerst. 



Neuroleon angustus Navas. 



This is A^. alcidicc Bks. 



Cymothales johnstoni Kirby. 



jMarks of wings as figured; antennae black on basal joint, then pale, 

 till near the tip where last few joints are brown; six or seven cross- 

 veins before radial sector in fore wing; two in the hind wing, eight 

 branches of radial sector, the seventh branch soon forks. 



Cymothales eccentros Walk. 



Marks of wings as in figure ; C. spcciosus Gerst. is very close to it, 

 but the stigmal mark is large and encloses a pale spot, while the two 

 pale spots in the apical mark are more widely separated, and the 

 upper mark of the median stripe is more rounded and contains a pale 

 spot, and the basal band is entire. The color of the antennae and 

 femur I is alike in the two species. 



Cymothales bouvieri v. d. Weele, 



The type has three cross-veins before radial sector in fore wings; 

 there are ten branches to the radial sector, the fourth branch soon 

 forked. The pronotum is dark, with two pale parallel lines, a sub- 

 marginal pale line each side, and an oblique line from the middle of 

 the submedian lines to the outer posterior corner. 



Nesoleon. 



A great number of species have been described in this genus, but 

 many are synonyms. 



Nesoleon variegatus Klug. 



Is as I have identified it, very similar to-A^. mystcriosus Gerst., 

 but not as heavily marked, and not showing the pale subapical streaks 

 in the wings ; the face mark is about the same, but the branches of 

 the interantennal mark do not enclose a spot as in A^ mystcriosus. 



Nesoleon virgatus Klug. 



Is practically the same as N. variegatus, but the wings are paler 

 and less marked; the lateral stripe of thorax above is broad.
